The two insulated beakers contain equal amounts of identical liquids. The temperature of Beaker A is 80°C. The temperature of Beaker B is 50°C. A copper rod connects the beakers. The system is then left alone for several hours. What would you expect to find when the system is examined after this time?
A. The temperature of Beaker A would be 50°C and the temperature of Beaker B would be 80°C.
B. The temperatures of the two beakers would be unchanged.
C. Both of the beakers would be at a temperature of 50°C.
D. Both of the beakers would be at a temperature of 65°C.
i think the answer is either a or c
I think you are guessing. if they are exactly the same, the amount of heat one loses changes the temp the same amount as the one gaining.
i think it is just a
The correct answer is A. The temperature of Beaker A would be 50°C and the temperature of Beaker B would be 80°C.
After several hours, heat will transfer from the hotter beaker (Beaker A) to the colder beaker (Beaker B) through the copper rod until they reach thermal equilibrium. Thermal equilibrium means that both objects have the same temperature. Therefore, the temperatures of the two beakers will equalize, resulting in the temperature of Beaker A decreasing to 50°C and the temperature of Beaker B increasing to 80°C.
To answer this question, we need to understand the concept of heat transfer and thermal equilibrium. Heat tends to flow from regions of higher temperature to regions of lower temperature until both regions reach the same temperature, which is called thermal equilibrium.
In this case, Beaker A has a higher temperature than Beaker B. When the copper rod connects the two beakers, heat will start to flow from Beaker A to Beaker B. This is because heat always moves from hotter objects to cooler objects.
Given enough time, the heat transfer will continue until both beakers reach the same temperature. Therefore, we can conclude that the temperatures of the two beakers will eventually equalize.
Based on this understanding, the correct answer would be:
C. Both of the beakers would be at a temperature of 50°C.
This is because heat will continue to transfer until thermal equilibrium is achieved, resulting in both beakers having the same temperature.
